Are there certain types that have a better carbon footprint?

If you’re concerned about your insulation’s environmental impact, look for materials that are made from recycled materials such as glass wool (often made from recycled glass), polyester products (often made from recycled plastic bottles) and natural sheep wool.

These insulation types help to reduce the amount of virgin material used, which means less energy is used to make them and therefore have a lower carbon footprint.
